Gday good folks.
Wondering if the collective can shed some light on trouble I’m having with
EOTopo.
I’m running it on a Samsung Android tablet and initially all worked as advertised.
However, last two trips out, I’ve found the position/tracking on the map continually freezes position.
If I go back to the
home page, then return to the map it picks up where I actually am and straight lines the snail trail from where it froze.
Has anyone else experienced this and can shed some light on why it’s happening?
Cheers

Hi Daryl,
I few things spring to mind, but Im no tech guru.
Are you using
Exploroz Traveller or using EO Topo with another app?
How long since you have done a complete reboot of your tablet?
Helps to close the app from time to time.(Traveller)
Disable the
treks filter if you have it enabled.(Travellar)
How many other apps did you have running in the back ground at the same time?
Is the memory on your tablet nearly full?
Regards
TrevorDavid

Have not used EOTopo with tracking, Daryl, but have similar occurrences with Hema 4WD maps on an old iPad. The unit can go to sleep, and if you don’t notice immediately, you start getting straight tracks.
You need 2.4A USB outlets for charging, cancel any time out settings, switch on flight mode & reduce brightness to some degree. And of course, one has to turn on tracking as one leaves last night
camp sites! A number of my tracks often have a gap, after leaving
camp.

Hi there, I can offer you a few things to look at:
1. Go to your device Settings and
check for a Battery Saving feature that might be turning off your GPS when the app is in the background, or gone to sleep.
2. Do you have the Map Screen Settings in the app using the "Stay Awake" feature? This option will override your normal device sleep function to ensure the map screen is always active if that's what you want. It only does this on the map screen and only when you have gone into the app Settings and turned on this feature.
3. I actually suspect this is what is happening - If you let your app run in the background and then wake it up, the map screen may take up to a minute to fully wake up - it takes a while and you have to be patient but if you watch carefully, the "straight line" snail trail will actually start to correct itself (catch up) with the stored positions it has been collecting whilst in the background. At first the map will appear drawing a fast straight line - but this will then begin to redraw itself as it compiles all the data it was storing whilst asleep. If this is the case - just be patient and let it "catch up". This is deliberate and allows the app to conserve
battery power when in background.

EOTraveller/
EOTopo is the only thing running on the tablet and is always on, never allowed to sleep.
It seems to happen most often when the vehicle has been stationary, then I move off. I come to the next
track intersection or geographical feature and look at the map and my position hasn’t moved. Hit the
home button at the top, then return to the map and the snail trail straight lines to current position and stays like that.
Other times I will be driving looking for a turn or feature and not realise the map has frozen and I go past thinking I’m not there yet, stop and do the above procedure to find I’ve missed my turn or feature.
I’m using the app with GPS only, as there is never any mobile service in the areas I’m poking around in,
Vic high country and surrounds mostly.
Cheers

HI Daryl,
It sounds like your device is running out of RAM or you have a setting in the device which is switching off your GPS (eg. a security/anti-virus app or something similar), or the Battery Saving feature in the Android operating system is turning off the GPS - all these things can and do happen to people out of the blue so please carefully
check your device for these sorts of issues.
With RAM - this issue could occur if you aren't regularly closing your apps (ie. overnight) and then giving the app a chance to reboot (clears out cache and refreshes RAM) when you launch it the next day.
So
check that you are not just mistakenly pushing the app to the background instead of correctly closing the app.
(ie. using the back button to shut down the app only disables it and pushes it to the background but doesn't' actually close it. ). The exact method to close an Android app varies from device to device and is dependent on the version of the Android operating system you have - up until Android 10, you would tap the left softkey and then press Close all apps, or just select one app to close by swiping it away.
I'm also interested to know which version of the Android operating system is running on your device? In our experience the really strange issues like this that don't make much sense, only seem to occur on devices that are running very old versions of the operating system, ie. be aware that once Android stops supporting a version, you no longer get the bug fixes and security updates and that can mean all manner of things can upset your system and makes it impossible for us to know how to troubleshoot. Can you get an update for the Android operating system on this device?
